' BED ATTAGHMENT.

Application filed January 5,1923. Serial No. 79,378.

- My invention relates to attachments for beds by which the'occupant ofthe'bed can be supported in a sitting posture or in various intermediateinclined"positions. 4

7 It is a purpose of my invention to provide a bed attachment of theabove described character which, in its applied position to a bed, iscapable of operation by the .oc-

cupant of the bed toraise himself to any inclined position desiredtO'tLISltiJlIIg posture and whereb the necessit of other er-. 3

Similar reference characters refer to similar parts in each of theviews.

Referring specifically to the drawings, my

invention, in its present embodiment, is

shown in Figure 1 as comprising a stationary frame 15 formed of metal orother suit-f able material and which is U-shaped, with a movable frame16 also of U-form pivotally connected at its free ends to the free endsof the stationary frame by means of hinges 17 so that the, movable frameism- V p'able' of upward swinging movement to occupy an upright positionor intermediate inclined positions. Th s movable frame is provided withany suitable type of. bed

spring 18, in order that it-may resiliently support the head end portion'ofa mattress at curved farm 19 is secured betweenits ends tothe forwardend of the movable frame 16 by means, of a bracket 20, the curvature ofthe arm 19'being such, that in its movement with the movable frame itwill inaintain operative engagement withfa pair of spaced rollers 21mounted onthe for-' v ward end of :the'station'ary frame 15'. This armis tubular in form, as, clearly shown in e y Figures 1 and 2, and forthe purpose of receiving flexible means adapted to be =se* cured to thest'ationaryframe" and'so oper-? ated as to effectelevation of-thear'manol; hence, the movable frame'f'lhis meansfin the present instance,comprises single length of l'l'exiblefsteel tape 22 securedfbyj "meansof a bracket at its lower end to thefforward end of the stationary frame15 at a point .betweenfthe rollers21. From this connection with thestationary frame, the tape passes around-a roller 24 mounted on thelower end of the arm 19, andthence" upwardly through the armto' awindlassor reel'25 ,to which it is securedandabout which itiswound.This'ree125fas shown in Figure 4, is' rotatably mounted 'upon' a'stuba'xle 26 secured 111 the arm, and formed, integral 'wlth the reelsaworni gear 27 which constantlyvnieshes with a wormlshaft 28 iournale'dinthe arm andprovided atits outer end with a crank- 29 by-wh'ich theshaft can be manuallyfrotated and through the medium of the worm geareffect rota tion of the reel,fas'. desired.' As shown in Figure 6, theshaft-28 may constitutepart of an electric motor30,w'ith the motor pro-j3 viding power operated means for "actuating;

the shaftand,hence, for rotatingthe reel;

In the applied position of the attachment,

as shown in l igure l, the stationaryffframe 15 is bolted or otherwisesecured to a bed spring frame 31, with the movable frame uppermost topermit elevation positioned thereof and with it the headsection of themattress 7 With the attachment applied, 7

the arm 19 is positioned atthe head end of the bed andnormally extendsabove the" mattress but within reach of an occupant of the bed, sothathe: may readily grasp" and operatethe crank 29 to rotate thereel.

25 to cause winding of the steel tape 22 thereon. ,As the lower end ofthetape is securedto the-stationary frame, it will be] manifest thatupon winding the tape upon 1 the reelan upward pull is exerted on thearm 19 to elevatethe latter, and as the mov- "able frame is secured tothe armit' will -eposzing on theqmattress. ticnlarly'noted that thecrank 29 occupies "a fixed positionwvith respect-to the mat-7 of theoperator.

Itis to be understood that the cooperation 'of the worm wheel and wormshaft is such that the reel 25 frictionally locked in any positionwhereby unwinding of the take from the reelisprevented, irrespective ofthe p'ositionbf the movable frame. lVhen employing the motorESO toactuate the shaft 7 28fitflwillb'e understood that a switch (not thespiritfand scope 0 shown) in the hands ofthe occupant may be closed tosupply current to the motor and v in the use of alternating current forthe 1notor,- apole changing switch can be provided.
